Oxo-biodegradable polythene now in sri lanka

There is a factory now in sri lanka to make oxo-biodegradable polythene which can replace environmentally hazardous normal polythene. Plastic Packaging (Pvt) Ltd (PPCL) is the company which manufactures oxo – biodegradable. It can carry frozen food and heavy items. When you throw it away after using, it degrades fast and disappears within a short period under the heat, sunlight or in any other place where oxygen is available. Oxo-biodegradable polythene is water-proof, can be used in the rain and carry wet things such as ice cream, fish and meat.

The degradation time period of oxo-biodegradable bags can be shortened or lengthened depending on the percentage of additives, added to the chemical structure. However, according to the manufacturing process, oxo-biodegradable bags degrade within six to 12 months. Oxo-biodegradable bags are manufactured with a high quality additive called PDQ-H which is imported from the USA.

Bio-degradable polythene was found to generate toxic compounds upon degradation that were much worse than the polythese itself as far as the environment is concerned. Has this material avoided the problem or is it the "same old wine in a new bottle"?
